Question

A device that produces electricity by transforming chemical energy into electrical energy is called a battery. transformer. none of the given answers If you connect two identical storage batteries together in parallel, and place them in a circuit, the combination will provide twice the voltage and the same total charge that one battery would twice the voltage and twice the total charge that one battery would half the voltage and half the total charge that one battery would. half the voltage and twice the total charge that one battery would. the same voltage and twice the total charge that one battery would. An electron is placed in a constant electric field of 4.5 Times 10^4 N/C. What is the force on the electron? If the electron is released from rest, what is its speed after 3.0 ps?

Explanation / Answer

Batteries transform chemical energy into electrical energy.

Batteries have three basic components.

Electrons will flow when the positive and negative terminals are connected because of this flow chemical reactions occur at the electrodes. Electrons at the anode which flow to the cathode due to this reactions.

b) Same voltage and twice the total charge that one battery would. If the cells are connected in series then the voltage increases and the currrent remains the same.

c) We know that the electric field, E= F/q

F=Force

q= charge

F=E*q

F=4.5*104*1.6*10-19=7.2*10-15 N

Force, F=ma

a=F/m=7.2*10-15 N/9.1*10-31=7.91*1015 m/s2

a=v/t

v=a*t

Velocity,v=7.91*1015 m/s2*3*10-12s=2.37*104 m/s
